1624	add waveform filter for video	dericed		"For video inspection it could be helpful to have a waveform filter for video. I can replicate this by using yuvdiag (http://www.silicontrip.net/~mark/lavtools/yuvdiag.c) with mjpegtools and running:

{{{
ffmpeg -f lavfi -i mandelbrot -pix_fmt yuv420p -f yuv4mpegpipe - | ./yuvdiag -l | ffplay -i -
}}}

I'd recommend allowing options to select Y, U, and/or V individually to show either overlaid or in parade mode.

I uploaded an output of the above command here: www.youtube.com/watch?v=HXbLNbT8NRQ"	enhancement	closed	wish	avfilter	git-master	fixed					0	0
